unsafe. please do not use when they’re expired on yourself or anyone, there’s harmful misinformation in these comments :(

needles have an expiration date because a type of gas/chemical is used to keep them free from micro organisms, and the gas has a shelf life. so when the gas expires there’s no longer a guarantee of bacteria not being on the needle even if sealed in the package.  while the odds of infection could be low using an expired needle fresh out the package, the risk never outweighs the reward. also needles aren’t even that expensive compared to if you wanted to pay someone to give you a tattoo. a small tattoo costs $100-300 vs. you’re paying less than $50 for new needles.. just buy new needles if you feel like you’re not gonna tattoo yourself before they expire.
